对大振幅磁声波中的离子轨道进行了数值和分析研究。轨道分为三种基本类型。在第一种类型中，离子穿过波而不反射，并且不会获得太多能量。在第二种类型中，它们被反射一次并在波法线方向上加速。在第三种类型中，它们被反射多次并在平行于波前的方向上加速。讨论了这些类型反射的条件并评估了加速离子的能量。
Ion orbits in a large-amplitude magnetosonic wave are studied numerically and analytically. The orbits are classified into three basic types. In the first type, ions pass through the wave without reflection and do not gain much energy. In the second type, they are reflected once and are accelerated in the direction of the wave normal. In the third type, they are reflected several times and are accelerated in the direction parallel to the wave front. Conditions for these types of reflection are discussed and the energies of accelerated ions are evaluated.
